Main Trade Route
The waters of the inner sea are well-traveled and have been mapped many times over the centuries. Unfortunately, maps differ, often making the exact location of any particular island difficult.
The central trade route is the most heavily traveled area. It encircles the largest of the city-states, where complex seaports serve as trade hubs to smaller island nations. Multiple points along the corridor are patrolled by military ships to prevent piracy and espionage.
